The displacement component displaces the mounting device in the shaft using the support member, wherein the carrier component is supported by an upper support roller on a support wall of the shaft during the displacement in the shaft. The support member generates a diagonal pull perpendicular to the support wall surface. The mounting system also has a compensating element that counteracts a tilting of the carrier component about the upper supporting roller perpendicular to the support wall during the displacement in the shaft.

DETAILED DESCRIPTION
(21) FIGS. 1 and 2 show a mounting system 1 without a compensating element which is designed and arranged such that, during a displacement of a carrier component 3 in the elevator shaft 103, it counteracts tilting of the carrier component 3 about the upper support roller 21 in the direction of (toward) a support wall 108. FIGS. 1 and 2 serve to explain the technical problem, which is solved by the combination of a diagonal pull of a support means with respect to the vertical in the direction of the support wall and a compensating element.
(22) FIG. 1 shows an elevator shaft 103 of an elevator system in which a mounting system 1 is arranged. The mounting system 1 has a mounting device 5 comprising a carrier component 3 and a mechatronic installation component 7. The carrier component 3 is designed as a frame on which the mechatronic installation component 7 is mounted. Said frame has dimensions that allow the carrier component 3 to be displaced vertically inside the elevator shaft 103, thus along the vertical 104, i.e. to travel to different vertical positions on different floors within a building, for example. In the example shown, the mechatronic installation component 7 is in the form of an industrial robot that is attached to the frame of the carrier component 3 so as to be suspended downwardly. In this case, one arm of the industrial robot may be moved relative to the carrier component 3 and, for example, displaced toward or away from a shaft wall 105 of the elevator shaft 103.
(23) The carrier component 3 is connected, by means of a steel cable acting as a support member or support means 17, to a displacement component 15 in the form of a motor-driven cable winch that is attached at the top of the elevator shaft 103 to a stopping point 107 on the ceiling of the elevator shaft 103. By means of the displacement component 15, the mounting device 5 can be vertically displaced inside the elevator shaft 103 over an entire length of the elevator shaft 103.
(24) The mounting device 5 further comprises a fixing component 19 by means of which the carrier component 3 can be fixed inside the elevator shaft 103 in the lateral direction, i.e. in the horizontal direction. The fixing component 19 on the front side of the carrier component 3 and/or the prop (not shown) on a rear side of the carrier component 3 can be displaced outward to the front or the rear for this purpose, and thus press-fit the carrier component 3 between walls 105 of the elevator shaft 103.
(25) The industrial robot can be coupled at its unsupported end to various mounting tools (not shown). The mounting tools can differ with regard to their design and their intended use. Said mounting tools allow mounting steps to be carried out semi-automatically or fully automatically in a fixed state of the mounting device.
(26) A magazine component (not shown in more detail) may also be provided on the carrier component 3. The magazine component can be used to store components to be installed and to provide the industrial robot 7. The magazine component can accommodate for example various components, in particular in the form of different profiles, which are to be mounted on shaft walls 105 inside the elevator shaft 103, in order, for example, to be able to fasten guide rails for the elevator system thereto. The magazine component may also be used to store and provide screws, which can be screwed into prefabricated holes in the shaft wall 105 by means of the industrial robot 7.
(27) Support rollers (not shown in FIG. 1) are also provided on the carrier component 3, by means of which rollers the carrier component 3 is guided during a vertical displacement inside the elevator shaft 103 along a shaft wall, which is referred to in the following as a support wall 108. The support wall 108 is, in this case, the shaft wall opposite the door openings 106 of the elevator shaft 103. The support rollers roll during the displacement of the mounting device 5 on the support wall 108. Depending on the arrangement of the support rollers on the carrier component, one to up to in particular four support rollers can be provided.
(28) According to FIG. 2, the carrier component 3 has a pair of upper support rollers 21 and a pair of lower support rollers 22. The upper support rollers 21 are arranged in an upper region and the lower support rollers 22 in a lower region of the carrier component 3. In FIG. 2, the mounting device 5 is arranged in a lower region of the elevator shaft 103, therefore prior to an upward displacement. In this case, the carrier component 3 is at a first distance s1 from the displacement component 15. The support means 17, which is fixed directly to the carrier component 3 and by means of which the displacement component 15 can displace the mounting device 5 in the elevator shaft 103, has a pull α in the direction of the support wall 108. Said pull α corresponds to the angle enclosed by the support means 17 and the vertical 104 in the direction of the support wall 108. Due to the pull α, a retaining force acting on the carrier component 3 via the support means 17 has a horizontal component 39 in the direction of the support wall 108. Since a force introduction point 38 at which the retaining force is introduced into the carrier component 3 is arranged above the upper support roller 21, in particular above a rotational axis (not indicated) of the upper support roller 21, the horizontal component 39 of the retaining force leads to a torque 23 in the counterclockwise direction about the upper support roller 21. The force introduction point 38 is the point at which a suspension element (not shown in more detail), for example in the form of a hook or an eyelet, on which the support means 17 is suspended is fixed to the carrier component 3. The torque 23 is thus oriented such that, when of an appropriate magnitude, it can lead to lifting of the lower support rollers 22 and can thus lead to the carrier component 3 tilting about the upper support roller 21 in the direction of the support wall 108. The horizontal component of the retaining force in the direction of the support wall 108 ensures that at least the upper support rollers 21 do not lift off from the support wall 108 and thus the mounting device 5 cannot swing freely in the elevator shaft 103. Swinging of this kind can lead to the mounting device 5 striking one of the shaft walls 105 and to the mounting device 5 and the shaft wall 105 thus being damaged.
(29) Compared with FIG. 2, the carrier component 3 in FIG. 3 is at a considerably shorter first distance s1* compared with the first distance s1 in FIG. 2, i.e. the mounting device 5 has been displaced upward in the elevator shaft 103 by the displacement component 15. Since the mounting system 1 in FIG. 2 and FIG. 3 does not have a compensating element and nothing has changed in terms of the connection between the displacement component 15, support means 17 and carrier component 3, the shorter distance s1* results in a significantly greater diagonal pull α* of the support means 17 in the direction of the shaft wall 108. The greater diagonal pull α* leads to a greater horizontal component of the retaining force in the direction of the support wall 108, and this leads to a significantly greater torque 23* about the upper support roller 21. In the example shown, the torque 23* is so great that the lower support rollers 22 lift off from the support wall 108 and the carrier component 3 tilts about the upper support roller 21 in the direction of the support wall 108. In the process, the mounting device 5 can strike the shaft wall 105, which can lead to the mounting device 5 and the shaft wall 105 being damaged.
(30) The mounting system 1 according to FIG. 4 has a compensating element 24 which is designed and arranged such that, during a displacement of the carrier component 3 in the elevator shaft 103, it counteracts tilting of the carrier component 3 about the upper support roller 21 in the direction of the support wall 108. In FIG. 4, the mounting device 5 has the same position in the elevator shaft 103 as in FIG. 2. The compensating element 24 has an energy accumulator in the form of a spring 25. The spring 25 is arranged between a stationary support element 26 and the displacement component 15, which is designed in this case to be movable in a direction that is transverse with respect to the support wall 108. As described, on account of the pull α of the support means 17 a horizontal component of the retaining force acts on the carrier component 3, which has to be supported by the displacement component 15 in the opposite direction, i.e. against the spring 25. The spring 25 thus acts on the displacement component 15 with a retaining force in the direction perpendicular to the support wall 108. In FIG. 4, the displacement component 15 is at a second distance s2 from the support wall 108.
(31) If the mounting device 5 is now displaced upward, the horizontal component of the retaining force on the carrier component 3 increases, and thus the force that has to be supported by the displacement component 15 against the spring 25 also increases. This leads to compression of the spring 25 and thus to a movement of the displacement component 15 away from the support wall 108. This movement of the displacement component 15 in turn counteracts the increase in the pull α of the support means 17 in the direction of the support wall 108. In the process, an equilibrium is constantly set which is determined mainly by the characteristic of the spring 25. By calculations or simple experiments, the spring 25 can be designed such that tilting of the mounting device 5 can be reliably avoided.
(32) FIG. 5 shows the mounting system 1 from FIG. 4 after completion of the upward displacement of the mounting device 5. The pull α of the support means 17 in the direction of the support wall 108 is approximately the same as in the position of the mounting device 5 in FIG. 4, and thus much weaker than the diagonal pull α* in FIG. 3, i.e. without the use of a compensating element. This was achieved by a movement of the displacement component 15 in the transverse direction away from the support wall 108 and thus by compressing the spring 25. In FIG. 5, the displacement component 15 is at a second distance s2* from the support wall 108, which distance is significantly greater than the second distance s2 in FIG. 4.
(33) In the mounting system 1 according to FIG. 6, a compensating element 124 is arranged on top of the carrier component 3. The support means 17 is fixed to the carrier component 3 by means of a suspension element 127 that is movable in the direction perpendicular to the support wall 108. The compensating element 124 has two springs 125 which are arranged on opposite sides of the suspension element 127 with respect to the support wall 108 and thus each exert a retaining force on the suspension element 127. The ends of the springs 125 opposite the suspension element 127 are fixed in position with respect to the carrier component 3 in a manner not shown in more detail. In FIG. 6, the suspension element 127 is at a third distance s3 from the support wall 108.
(34) If the mounting device 5 is now displaced upward, the horizontal component of the retaining force on the carrier component 3 increases and the suspension element 127 is pressed in the direction of the support wall 108 and displaced against the force of the springs 125 in the direction of the support wall 108. This movement of the suspension element 127 in turn counteracts the increase in the diagonal pull α of the support means 17 in the direction of the support wall 108. In the process, an equilibrium is constantly set which is determined mainly by the characteristic of the springs 125. By calculations or simple experiments, the springs 125 can be designed such that tilting of the mounting device 5 can be reliably avoided.
(35) FIG. 7 shows the mounting system 1 from FIG. 6 after completion of the upward displacement of the mounting device 5. The pull α of the support means 17 in the direction of the support wall 108 is approximately the same as in the position of the mounting device 5 in FIG. 6, and thus much weaker than the diagonal pull α* in FIG. 3, i.e. without the use of a compensating element. This was achieved by a movement of the suspension element 127 in the direction perpendicular to the support wall 108. In FIG. 7, the suspension element 127 is at a third distance s3* from the support wall 108, which is significantly shorter than the third distance s3 in FIG. 6.
(36) In the mounting system 1 according to FIG. 8, a suspension means 228 is arranged between the support means 17 and the carrier component 3, the support means 17 and the suspension means 228 being connected by means of a connecting element 229. The suspension means 228 is designed as a cable loop of which the ends are connected to the carrier component 3 on opposite sides with respect to the support wall 108. A compensating element 224 is arranged on the suspension means 228 and is designed to be able to move the connecting element 229 relative to the suspension means 228. For this purpose, the compensating element 224 has an actuator 230 (shown only in FIG. 10) in the form of an electric motor, by means of which the connecting element 229 can be moved relative to the suspension means 228. The actuator 230 can drive a drive roller 231. The suspension means 228 extends between the drive roller 231 and a press roller 232. The press roller 232 is pressed by means of a spring (not shown) against the suspension means 228, which is thus pressed against the drive roller 231. If the actuator 230 now drives the drive roller 231, said roller rolls on the suspension means 228, as a result of which the position of the connecting element 229 with respect to the suspension means 228 and thus a fourth distance s4 from the support wall 108 can be set.
(37) The actuator 230 is actuated by a controller 237. The controller 237 sets said fourth distance on the basis of an inclination of the carrier component 3. An inclination sensor 233 is arranged at the bottom of the carrier component 3 in order to measure the inclination. The controller 237 measures the inclination and sets the fourth distance by means of closed-loop control such that the carrier component 3 is always oriented vertically, i.e. is not inclined. It is also possible for the controller 237 to set said fourth distance on the basis of the first distance between the displacement component 15 and the mounting device 5. For this purpose, the controller 237 can directly measure the first distance by means of a distance sensor (not shown). It is also possible for the controller to measure a distance from a bottom of the elevator shaft 103 and to determine the first distance therefrom. Moreover, it is possible for the controller 237 to detect how far the displacement component 15 displaces the mounting device 5 in the elevator shaft 103 and to determine the current first distance proceeding from a first distance prior to the displacement. To determine the currently required fourth distance, a table is stored in the controller 237, in which table the fourth distance is stored on the basis of the first distance. When the controller 237 has determined the current first distance, it can read out the currently required fourth distance from said table, and then set this using the actuator 230.
(38) In FIG. 8, the connecting element 229 is at a fourth distance s4 from the support wall 108. FIG. 9 shows the mounting system 1 from FIG. 8 after completion of the upward displacement of the mounting device 5. The pull α of the support means 17 in the direction of the support wall 108 is approximately the same as in the position of the mounting device 5 in FIG. 8, and thus much weaker than the diagonal pull α* in FIG. 3, i.e. without the use of a compensating element. This was achieved by a movement of the connecting element 229 by means of the actuator 230 in the direction perpendicular to the support wall 108. In FIG. 9, the connecting element 229 is at a fourth distance s4* from the support wall 108, which is significantly shorter than the fourth distance s4 in FIG. 8.
(39) FIG. 11 shows a compensating element 324 that is an alternative to the compensating element 24 from FIGS. 4 and 5. The compensating element 324 has an actuator 330 instead of a spring, by means of which actuator the displacement component 15 can be moved. The actuator 330 is designed as an electric motor which can extend and retract an actuating cylinder 333 acting on the displacement component 15. The actuator 330 is actuated analogously to the actuator 230 from FIG. 10 by a controller 337.
(40) FIG. 12 shows a further compensating element 424 that is an alternative to the compensating element 24 from FIGS. 4 and 5. The compensating element 424 also has an actuator 430, by means of which a deflection element 434 in the form of a deflection roller can be moved in a direction perpendicular to the support wall 108. The displacement component 15 is in this case stationary and arranged such that the support means 17 is guided horizontally out of the displacement component 15 and is then deflected downward by means of the deflection element 434. Moving the deflecting element 434 has the same effect as moving the displacement component 15 in FIG. 11. The actuator 430 is designed as an electric motor which can extend and retract an actuating cylinder 433 acting on the deflection element 434. The actuator 430 is controlled analogously to the actuator 230 from FIG. 10 by a controller 437.
(41) The deflection element in the form of a deflection roller could also be acted on, analogously to the displacement component in FIGS. 4 and 5, with a retaining force by means of one or two energy accumulators, in particular in the form of springs. In this case, the actuator and the controller could be omitted.
(42) FIG. 13 shows a compensating element 524 that is an alternative to the compensating element 124 from FIGS. 6 and 7. The compensating element 524 has an actuator 530 instead of a spring, by means of which actuator the suspension element 127 can be moved. The actuator 530 is designed as an electric motor which can extend and retract an actuating cylinder 533 acting on the suspension element 127. The actuator 530 is controlled analogously to the actuator 230 from FIG. 10 by a controller 537.
(43) The described controllers 237, 337, 437, 537 which actuate the actuators 230, 330, 430, 530 are designed in particular such that they actuate said actuators 230, 330, 430, 530 when the mounting device 5 is fixed in the elevator shaft 103 by means of the fixing component 19.
(44) The mounting system 1 according to FIGS. 14 and 15 has a very similar design to the mounting system 1 according to FIGS. 2 and 3, and therefore only the differences are discussed. The mounting system 1 according to FIGS. 14 and 15 also does not involve a change in terms of the connection between the displacement component 15, support means 17 and carrier component 3, and therefore in FIG. 15 a shorter distance s1* results in a significantly greater diagonal pull α* of the support means 17 in the direction of the shaft wall 108. In order to prevent tilting of the carrier component 3 about the upper support roller 21 in the direction of the support wall 108, the mounting system 1 has a compensating element 624. The compensating element 624 has an actuator 630 which is connected to a compensating weight 635. The compensating weight 635 can be moved relative to the carrier component 3 mainly in the horizontal direction by means of the actuator 630. Due to the movement of the compensating weight 635, a center of gravity 636 of the mounting device 5 can be moved and thus a fifth distance between the center of gravity 636 and the support wall 108 can be changed or set. The actuator 630 is actuated by a controller 637 such that the fifth distance between the center of gravity 636 of the mounting device 5 and the support wall 108 is increased when a first distance between the displacement component 15 and the mounting device 5 reduces. The actuator 630 is actuated analogously to the actuator 230.
(45) FIG. 14 shows the mounting system 1 prior to an upward displacement. The center of gravity 636 of the mounting device 5 is at a fifth distance s5 from the support wall 108. After the upward displacement of the mounting system 1 in FIG. 15, the fifth distance s5* is significantly greater.
(46) The mounting system 1 according to FIGS. 16 and 17 has a compensating element 724 which in principle functions in the same way as the compensating element 624 from FIGS. 13 and 14. The difference is that in the mounting system 1 according to FIGS. 16 and 17, the mechatronic installation component 7 in the form of the industrial robot is part of the compensating element 724 and is used as a compensating weight. The center of gravity 736 is in this case moved by a change in the position of the mechanical installation component 7, i.e. by means of a change in the position of the mechatronic installation component 7. FIG. 16 shows the mounting system 1 prior to an upward displacement. The mechatronic installation component 7 is arranged as close as possible to the support wall 108, resulting in a fifth distance s5 between the center of gravity 736 of the mounting device 5 and the support wall 108. During the upward displacement of the mounting system 1, the position of the mechatronic installation component 7 is continuously changed by a corresponding actuation by a controller 737 such that it is at an ever greater distance from the support wall 108. After completion of the upward displacement of the mounting system 1 in FIG. 17, the fifth distance s5* is significantly greater.
(47) In the mounting system 1 according to FIGS. 18 and 19, the upper support roller 21 is arranged on a spacer element 840 that projects upward from the carrier component 3. A force introduction point 838 at which the retaining force is introduced into the carrier component 3, is therefore arranged below the upper support roller 21, in particular below a rotational axis (not indicated) of the upper support roller 21. It would also be possible for the force introduction point to be arranged at the same level as the upper support roller. The horizontal component 839 of the retaining force thus extends below the support roller 21, resulting in a torque 823 about the upper support roller 21 which is in the opposite direction to the torque 23 in FIG. 2. The torque 823 cannot therefore lead to the lower support roller 22 lifting off from the support wall 108 and thus to the carrier component 3 tilting about the upper support roller 21; rather, the lower support roller 22 is pressed against the support wall 108 on account of the torque 823. The upper support roller 21, the spacer element 840 and the force introduction point 838 thus form a compensating element 829 which, during the displacement of the carrier component 3 in the elevator shaft 103, counteracts the tilting of the carrier component 3 about the upper support roller 21 in the direction of the support wall 108. In addition to the components mentioned, the compensating element may also comprise a suspension element (not shown), for example in the form of an eyelet, a hook or a through-opening of the carrier component.
(48) As can be seen in FIG. 19, an upward displacement of the carrier component 3 does not change the arrangement of the horizontal component 839 of the retaining force on the support roller 21, which component is greater compared with FIG. 18. As a result, the orientation of the torque 823 about the upper support roller also remains unchanged, and therefore there is also no tilting of the carrier component 3 in the direction of the support wall 108 during or after an upward displacement of the carrier component 3.
(49) Finally, it should be noted that terms such as “comprising”, “having”, etc. do not preclude other elements or steps, and terms such as “a” or “an” do not preclude a plurality. Furthermore, it should be noted that features or steps that have been described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above.
(50) In accordance with the provisions of the patent statutes, the present invention has been described in what is considered to represent its preferred embodiment. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
